Hyperacusis is an abnormal sensitivity to everyday sound levels or noises, with the accompanying sensitivity to high pitched sounds. The disorder is often chronic and usually followed by tinnitus or ringing sound in the ears in 40% of the people. While Hyperacusis on its own affects only 1 in 50,000 people, it’s more common among people with tinnitus.
